For current Housing Statistics in Livermore, Pleasanton, Dublin, Danville, San Ramon and other cities in Alameda and Contra Costa counties go to this link below - this our MLS that REALTORS use (obviously we log into the MLS and get more data, but this is where the public can go to and get stats):

The time is right for investors to buy property.  Looking at investing out of state?  Why?  You can buy a single family detached home here in the Bay Area for the same price as a comparable home in the Portland Metro Area.  And rents are higher here in California than in Oregon and other states.  Stay local, property manage your own property and create an even cash flow situation.  Remember, most people either invest for (1) Positive Cash Flow - which requires putting down a substantial amount of cash into the investment, or (2) Appreciation, or hopefully (3) A balance of Positive/or even cash flow AND Appreciation.  Appreciation happens over time.  Historically, property values have increased year over year.   Buy low, sell high - we are in a buyer's market.  REO's and short sales prevail in statistics in many areas surrounding the Bay Area.
